Chicago police have released video footage of a man parking his SUV before grabbing a woman and stabbing her as she walked to the Fullerton Red Line station Tuesday night in the Sheffield Neighbors community.

The 21-year-old woman was walking east around 10:50 p.m. in the 1200 block of West Webster Avenue when the man grabbed her neck and put her in a choke hold, Chicago police said in a community alert.

After the man stabbed her several times in the upper body, video shows her attacker fleeing west to Wayne Avenue and leaving heading north in a dark colored Cadillac SRX, police said. Earlier surveillance video shows the man parking the SUV.

The attacker never spoke to the woman and she didn’t know she was being followed, the alert said. He wore a black hoodie and black baggy pants, and was about 5-foot-9.

A GoFund me page has been set up to help the woman, whose condition had stabilized at Advocate Illinois Masonic Medical Center, police said earlier.

Anyone who recognizes the Cadillac or has information is asked to call Area Central detectives at 312-747-8380.
